From SaaS to GaaS: what it means for your ERP
Software you log into and operate is giving way to software that does the work and hands you the result. For accounting and ERP, that is a bigger change than the move to the cloud was.
The line that named a market
At Nvidia's GTC conference in March 2026, chief executive Jensen Huang told the audience: "Every SaaS company will become a GaaS company." SaaS is software as a service, the model almost every business application has used for 20 years. GaaS, as commentators have expanded it since, is agentic AI as a service: software in which AI agents do the work, instead of software that helps a person do it.
It is a short sentence with a long reach. It says the thing being sold is changing. Not the screen, not the login, not the seat, but the finished piece of work.
SaaS sells you a tool that a person operates. GaaS sells you the work itself, done by an agent, with a person approving what matters.
What actually changes
Take a task every business does every month: matching the bank statement to the books.
| SaaS | GaaS | |
|---|---|---|
| Who does the work | An accountant, inside the software | An agent, inside the software |
| What the person does | Imports the file, ticks each line, books what is missing | Reviews what the agent matched and prepared, and approves it |
| What you pay for | A seat per user, per month | Increasingly, the outcome: lines matched, bills booked, months closed |
| How you judge it | Is the screen easy to use? | Is the work right, and can I see why? |
The software still exists in both columns. What moves is who presses the keys.
The last row is the important one. When a person does the work, the software is judged on how easy it is to operate. When an agent does the work, the software is judged on whether the work is correct and whether a person can check it quickly. That is a different product, built to a different standard.
Why ERP is where this matters most
Most business software is a single task: send an email campaign, run payroll, track a support ticket. An ERP is the opposite. It is the record of everything a business does with money and goods: every sale, purchase, receipt, payment, stock movement, tax return and journal. It is also where most of the repetitive work in a finance team lives.
In a typical small manufacturer, the finance team spends its month on 5 kinds of work that an agent can prepare:
- Booking supplier bills from PDFs and emails, line by line, with the right tax.
- Matching the bank to receipts and payments, and preparing the ones that are missing.
- Reconciling input tax credit against what suppliers have filed.
- Chasing customers who are late, with the right amount and the right invoices.
- Explaining the numbers to the owner: why margin fell, where the cash went, what is due this week.
None of that requires judgement for most lines. All of it requires care. That combination is exactly what an agent is good at, as long as a person approves the result.
AI added on, or AI native
Almost every established ERP now has something called AI. In most cases it is a chat window placed on top of the old product: it can answer questions about a screen, or summarise a report. The work itself is still done the old way, by a person, in the old screens.
An AI native ERP is built the other way round. The agent is a first class user of the system, with its own rights, its own audit trail and its own place in every workflow. It prepares the document; the person posts it. It reads the bank file; the person approves the matches. It answers a question by working from the books themselves, and shows every figure it used.
A chat window over the old product. Answers questions about the screen. A person still does the work.
The agent prepares the work inside every workflow, under the same rights and audit trail as a person. A person reviews and approves.
The one rule that must not change
Accounting has something most software does not: a statutory audit, tax authorities and lenders who rely on the numbers. That puts a limit on how far GaaS can go in finance, and the limit is healthy.
Agents prepare, people approve. Nothing is posted to the books, filed with the tax portal or sent to a customer without a person pressing the button, and every agent action is in the audit trail with the reason it was taken.
This is not a brake on the idea. It is what makes the idea usable. An owner who can see every figure behind an answer, and who approves every entry, gets the speed of an agent and keeps the control of a person. That is the version of GaaS a finance team can actually adopt.
What about price?
Much of the GaaS conversation is about charging for outcomes instead of seats: per bill booked, per bank line matched, per month closed. For large companies with steady volumes, that can work. For small and mid sized Indian businesses, a fee that moves every month with volume is hard to budget, and most owners prefer to know what they will pay.
The likely answer for this market is a predictable subscription that includes the agent's work, rather than a meter on every action. The value is still the outcome. The bill just does not change shape every month.
5 questions to ask any ERP that says it has AI
- Does the agent do work, or only answer questions? Ask to see it prepare a document you would otherwise type.
- Can I see every figure behind an answer? An answer you cannot trace is an opinion, not accounting.
- Who presses Post? If the answer is the agent, walk away.
- Is every agent action in the audit trail? With who approved it and when.
- Does it know Indian tax? GST, input tax credit, TDS and electronic invoicing are not add ons for an Indian business. They are the books.
Niyantrak ERP: GaaS for Indian books
Niyantrak ERP, built in India by Niyantrak Consulting LLP, is an AI native ERP designed around exactly this rule. Its built in AI, called Controller, prepares the work and answers any question about your books, showing every figure it used. A person approves everything that is posted. Every company deserves a Controller; not every company can afford one. Niyantrak ERP puts one inside the books. The cloud edition is coming soon.
Questions and answers
What is GaaS?
GaaS, as commentators have expanded it after Nvidia's GTC 2026 keynote, means agentic AI as a service: software in which AI agents do the work, such as booking bills or matching the bank, instead of software that a person operates.
What is the difference between SaaS and GaaS for an ERP?
With SaaS, a person logs in and does the work inside the software. With GaaS, an agent prepares the work, such as bills, bank matches and reconciliations, and a person reviews and approves it.
Which ERP is built for GaaS in India?
Niyantrak ERP, built in India by Niyantrak Consulting LLP, is an AI native ERP in which its AI, Controller, prepares the work and answers questions from the books, while a person approves everything that is posted.
Can an AI post entries in the books on its own?
It should not. In a well designed AI native ERP the agent prepares, a person posts, and every agent action is in the audit trail.
Thinking about what your next ERP should do on its own?
Niyantrak Consulting LLP has spent years inside the month end of manufacturing and trading businesses, and has built an AI native ERP around what it found. A short conversation is enough to see where it fits.
